The Korean container port development under the master plan for national port development reveals a severe problem of excess supply of port facility in some ports. This paper, the authors analysed the second and the third master plan for national port development implemented in 2001 and 2011, and a revised plan in 2006, along with the amended predictions for container throughput. Furthermore, the effectiveness of the implementation of the initial plan, and the current situation of South Korea＇s main container ports of Busan, Gwangyang, Incheon, and Pyeongtaek ＆ Dangjin was examined. Through the analysis of port vitalizations, we have examined the actual problems for the prediction of container throughput. Also, this research analysed the functional difference of each port and organized the function of each one discriminatively. Therefore, identifies the problems, which arise with making the container throughput forecasts, which is a fimdamental aspect of existing port development policy, and suggest a direction for future port development by synthesizing the results of analysis.展开更多

The area is located in the southern Caspian Sea near the Anzali Port. Recorded wave data were obtained through directional spectrum wave analysis. Recorded wind direction and wind speed were obtained through the related time series as well. For 12-month measurements（May 25 2007-2008）, statistical calculations were done to specify the value of nonlinear auto-correlation of wave and wind using the probability distribution function of wave characteristics and statistical analysis in various time periods. The paper also presents and analyzes the amount of wave energy for the area mentioned on the basis of available database. Analyses showed a suitable comparison between the amounts of wave energy in different seasons. As a result, the best period for the largest amount of wave energy was known. Results showed that in the research period, the mean wave and wind auto correlation were about three hours. Among the probability distribution functions, i.e Weibull, Normal, Lognormal and Rayleigh, ＂Weibull＂ had the best consistency with experimental distribution function shown in different diagrams for each season. Results also showed that the mean wave energy in the research period was about 49.88 k W/m and the maximum density of wave energy was found in February and March, 2010.展开更多
